Scott was arrested between 10 p.m. and 10:20 p.m. at a residence in the Little Woods neighborhood in New Orleans East.

Members of a U.S. Marshals task force working with NOPD special operations took Scott into custody, I-Team sources said. No significant resistance was reported.

He was booked on 20 counts of attempted second-degree murder and taken to the Orleans Parish Prison at 1:39 a.m., according to Sheriff's Office records.

Scott was wanted in connection with the shootings of 19 people at the Mother's Day event. Two of the victims were children.

An NOPD official confirmed the arrest in a brief email.

"Akein Scott is now in NOPD custody," it read. "Picked up tonight in Little Woods. We have no further details at this time."

Surveillance cameras captured images of a young man stepping into the street and opening fire on the crowd, then running away. Police identified the shooter as Scott and obtained an arrest warrant.

"I would recommend strongly that Mr. Scott contact anybody who he is comfortable with to turn himself in," NOPD Supt. Ronal Serpas said in identifying the suspect on Monday.

Searches of numerous locations earlier in the week were unsuccessful.

It was not immediately clear what led police to Scott late Wednesday. Crimestoppers and the Bureau of Alcohol Tobacco and Firearms offered rewards totaling $10,000 for information leading to an arrest and indictment in the case.
